Looking to get a good Refractometer for a reef tank I'm building. I found this very affordable Refractometer on Amazon:
Automatic Temperature Compensation Sea Water Salinity Refractometer for Aquarium, 0% - 10% & 1.0 to 1.070 S.G. DUAL SCALE Hydrometer By AdeAdvancedOptics: Amazon.com: Industrial & Scientificoes anyone have this or recommend I purchase based on the description. Very similar items at other stores but much cheaper. Looks the same as the one sold at Bulk Reef Supply (Refractometer for reading salinity w/ Free Calibration fluid - Bulk Reef Supply) minus the calibration fluid but I believe I could just use distilled water for the Amazon unit. BRS also charges $10+ shipping unless I spend $175+ which I definitely can't do now for other items. Amazon shipping is free since I'm a Prime member.
Let me know your thoughts on the Amazon Refractometer. THANKS!
